STEVENSON, OF REDDING, CALIFORN1AY AXLE BOX AND SPINDLE.

Specification of Letters Patent.

Patented March 23, 1909.

Application led April 6, 1908. Serial No. 425,539.

To all whom 'it may concern:

Be it known that we, BENJAMiN E. STE- vnNsoN and MARY E. S'rnvENsoN, citizens of the United States, residing at Redding, in the county o'r'- Shasta and State of California, have invented certain new and useful 11nprovements in Axle Boxes and Spindles; and we do declare the following to be a lull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the Sarno.

rl`his invention relates to an improved construction of axle box and spindle, having means whereby the box is secured to the spindle in such manner as to prevent the entrance of dust or dirt, and to prevent the escape of the lubricating oils applied to the spindle.

A further object of the invention is to provide means to take up the wear of the arts, and to facilitate the application of the ubricating oil to the spindle.

lith these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be described and particularly pointed out in the appended clanns.

1n the accompanying drawin s, Figure l is a longitudinal vertical sectiona view of the box and hub showing the saine a plied to the spindle of an axle 3 and Fig. 2 is a ongitudinal sectional view of the box and the attaching nut.

Referring more particularly to the drawings, 1 denotes the spindle, which is rovided at its inner end with an annular lange, 2, which provides inner and outer shoulders, 3 and 4. Ada ted to be engaged with the spindle l, is a ox, 5, said box having a closed outer end, 6, and is provided at its yend with exterior screw-threads, 7. The inner end of the box is enlarged as shown at S, and in said enlargement is formed an annular recess, 9, of greater diameter than the bore of the box. The enlarged portion of the box is provided with exterior screwthreads and on said threaded end of the box is adapted to be screwed a retaining nut, l0, which is in the form of a cap, and 1s engaged with an axle of the vehicle immediately in rear of the liange, 2, of the spindle.

Between the inner shoulder, 4, formed by the flange, 2, and the inner side of the retaining nut, 10, is arranged a washer, 12, a similar washer, 13, being arranged between the l Shoulder, 3, and the adjacent shoulder I formed by the recessed portion of the enlargement, 8. By keeping the nut 1U screwed up tightly on the end ol the en larged portion of the spindle, all weer of the paris may be taken up and the endeise movement ol' the wheel prevented. Also on the threaded portion of the enlarged ond. S. of the box, is arranged a jan nid. il. which, when the retaininfy nut, l0, is srrcwrd up in position, may be locked by svn-wing the jam nut into engagement tliere',-.'itir ln the retaining nui, 1U, is formed :in oil hole, l5, through which lubricatingl oil may be readilyv introduced to the spindle. The box, 5, is Ylii'ied into a hub, 16, which may be of any suitable shape or construction, und is here shown as forined of wood and provided with an. outer shell or casing, 1T, ol' thin metal, The hub is provided with a series oi' radially projecting sockets, 1S, to rereive rho spokes of the wheel. The hub is held against rotation on the box, 5, by means of radially projecting lugs, 19, which are formed on the outer side of the box adjacent lo the onlarged inner end of the same. At the inner end of the hub is arranged an end plate or colll r, 20, and the inner end of the easing, 1T. is extended beyond the collar, 20, to project over and cover the space between tho collar and the jam nut, 14, thus preventing the entrance of dirt between these parts. Adapted lo be screwed onto the ihroiuled outer end, 7, of the box, is a nut, 21, on which is preferably arranged an ornamental cap, 22. 'lhe forward end of the shell, l?, is extended and projects a suitable distance beyond the end of the box and the cap, 22, and provides a ferrule or annular guard. 223, for the end of the hub.

A box closed at its outer end and constructed at its inner end as herein sho n :md described, will positively prevent the ontrance of dust or dirt to the bearing portion of the spindle, and will also prevent the loss or waste of the lubricating oil which is introduced to the box through the retaining nut, 10, as hereinbefore described` Frein the foregoing description, taken in connection with the accompanying drawing, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may he resorted to without departing from the principle or sneriliring any of the advantages of the invention :is defined in the appended l rlaiilns.

Having thus described our invention, what we elaiin es new, and desire to Seenre by Letters-Patent, is:

1. The eombinetion with an exe Spindle, of e box revolnbly mounted thereon, seid box heving a Closed end threaded outer ond, :i oep nut eerewed onto the threaded outer end, en exteriorly threaded reeessed enlargement, on the inner end of the box, :t enpslniped retaining; nut :adapted lo be serewed onto the :seid threaded enlargement to cover und ineloee the seine, seid nul having formed therein un oil hole wherebyY lubricating oil introduced into the Spindle. :1 juin nut to lock seid retaining' nut in its adjusted position, n hub arranged on seid box, and ineens to cover the space between seid jmn nut and the inner end ol' the huh. 1

2. The eoinbinntion with :in axle spindle having :in minulur lienge et its inner end, ol' n box revolnbly mounted on Said spindle, said box having a closed threaded outer end, and an enlarged exteriorly threaded inner end, a cup-shaped retainin nut arranged on the axle and adapted to Ae screwed into engagement with said enlarged end of the box whereby the latter is covered end whereby the endwise weer of the parte may be taken up, a jam nut to look Said retaining nut in its adjusted position, eu hub arranged on said box, an end pleite on the inner end of said hub, a Shell or easing arranged around Said hub and projeetingT beyond the inner ends oi the Saline and over the spare between said end plete and seid juni nut to prevent the entrance of dirt between Suid parte.

In testimony whereof We have hereunto set our hands in presenee of' two subscribing Witnesees.
